CPA firms have the same perennial and unyielding mandate as any other business: maximize efficiency, mitigate risk and fund innovation. We live in an era of digital transformation where agility is the currency of success. Yet, as firm leaders scour the general ledger for savings, many are overlooking a massive category of financial waste simply hidden in plain sight.
Invisible excess costs are draining budgets across the enterprise. Recent industry insights suggest that less than half of companies have complete visibility into their total corporate services spend. This lack of oversight allows "zombie" costs—expenses for services that are obsolete, redundant or unmanaged—to fester. While the focus is often on high-profile investments, two flashing red lights are currently blinking on the accountant's dashboard, often ignored until they cause critical damage: the retirement of legacy copper networks and the rising tide of utility volatility driven by AI adoption.
The first major leak in the budget comes from a century-old technology that refuses to die quietly: the Plain Old Telephone Service. For decades, POTS copper landlines were the backbone of business communication. Today, they are a financial liability hanging by a thread.
The FCC has greenlit the retirement of these copper networks, acknowledging that the infrastructure is degrading and no longer sustainable. Yet, analysts predict that up to 28 million POTS lines remain active in the U.S. alone. In the corporate world, these lines often sit forgotten—connected to elevators, alarm systems, fax machines and emergency call boxes.
These are "zombie" lines. They may no longer be in active use, or they may be redundant, yet the invoices continue to arrive. Worse, carriers are aggressively raising prices on these remaining lines to force migration, meaning many firms are paying a significant premium for obsolescence. I have seen enterprises managing thousands of locations where "phantom" lines were auto-renewing simply because no one had the data to prove they were disconnected.
Beyond the monthly operational expense, there is a significant risk cost. Aging copper is susceptible to weather damage and degradation, leading to outages that disrupt business continuity. In a digital economy, downtime represents not just an inconvenience but a direct hit to revenue and reputation. One may as well pay top-dollar maintenance on a vehicle that has already been recalled.
If copper lines represent the ghost of infrastructure past, utility costs represent the volatile storm of the future. As organizations race to adopt AI and high-performance computing, their energy demands are skyrocketing. AI processing power requires massive amounts of electricity and cooling, turning what was once a predictable utility line item into a variable cost driver.
However, the problem is more one of administration than consumption, as utility expense management is notoriously decentralized. In many large enterprises, utility bills—electricity, water, gas—are processed at the local level, often manually. They pass through accounts payable without rigorous audit. This manual friction is costly; some organizations employ dozens of staff members solely to process thousands of paper bills monthly, a task that invites human error.
This lack of visibility serves to hide waste. Without centralized data, it is impossible to detect anomalies. Smart expense management platforms often flag billing issues or consumption anomalies—such as water leaks or meter errors—in nearly one-third of managed accounts. Without this oversight, companies bleed hundreds of thousands of dollars annually in overcharges and physical waste.
To plug these leaks, leaders must move from reactive payment processing to proactive expense management.
Look for services that provide usage transparency. Technologies that utilize AI to ingest and analyze billing data can instantly flag "zombie" services—identifying lines with zero usage that are still being billed or utility accounts for closed locations.
Also consider heavy vendor consolidation. The administrative burden of managing thousands of invoices from hundreds of different carriers and utility providers is a hidden OpEx drain. By consolidating vendors or utilizing managed services partners, organizations can reduce the "swivel chair" effect—eliminating the need for large teams just to process paper. In some cases, automation can reduce the headcount required to manage these bills from two dozen people down to one or two, freeing up talent for higher-value strategic tasks. Furthermore, consolidation provides "one throat to choke" for accountability and significantly increases leverage during contract negotiations.
At the same time, consider modernizing old legacy structures. While this is often viewed as a capital expenditure hurdle, moving away from copper allows people to shift to OpEx models. For example, replacing copper lines with digital wireless interfaces (such as LTE and 5G) often results in immediate monthly savings that fund the transformation itself.
And while we're focused on physical infrastructure here, don't forget how this logic also applies to the digital realm. "Shadow IT"—SaaS subscriptions purchased by individual departments without IT or finance department approval—creates similar invisible costs. It is not uncommon for a company to be paying for duplicate project management tools or cloud storage that has been abandoned by the users. Implementing strict procurement policies and using expense management platforms to track software utilization ensures the company isn't paying for "zombie" licenses that no one logs into.
The "invisible ledger" is real, and in a tight economic environment, it is unacceptable. The retirement of copper and the energy demands of the AI era are inevitable market forces. The ones who will succeed are those who treat these not as IT problems, but as financial imperatives. By shining a light on these dark corners of the budget—consolidating vendors, automating audits and modernizing infrastructure—finance leaders can do more than just cut costs. They can recover the capital needed to fund the next generation of growth and ensure their infrastructure is as resilient as their balance sheet.
